Hi,I'm between those amps: Aguilar tone hammer 500, TecAmp puma500 and Epifani Ul501. I would like to know how those amps compare and contrast which other. I want to pair them like this: tone hammer + 2 berg. Hd112 pumma + tecamp M212 Epifani + 2 ul112. the amp I used for the past 8 years its one Hartke HA3500 + Hartke4x10.It's time for something new!
